The structural layers of the sun are shown in the cross-sectional diagram. An image of six concentric circles is shown. The six layers thus formed are of varying thickness. The layers in order from inside out are labeled, A, B, C, D, E, F.

Which layer represents the corona?

C
D
E
F

The Corona is the outermost atmosphere of the sun, there is no picture so I can only guess that it's the 6th layer.  

I hope this helps!

f!

Explanation:

the corona is the outermost layer!

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
